300-Mesh Slag Vertical Grinding Mill: Revolutionizing Industrial Byproduct Processing

The mining and metallurgy sectors generate massive amounts of slag, a challenging byproduct that can be transformed into high-value additives when processed to 300-mesh (48 micron) fineness. Modern vertical roller mills (VRM) have emerged as the most efficient solution for this application. Here's why:

Why Vertical Mills Outperform Traditional Grinders for Slag?

1️⃣ Superior Particle Distribution – Dynamic classifiers achieve 98% <300-mesh vs. 85-90% in ball mills
2️⃣ Moisture Tolerance – Handles 8-12% wet slag without pre-drying (critical for LD/BOF slag)
3️⃣ Wear Resistance – Reinforced grinding rollers last 8,000+ hours with highly abrasive materials

Technical Highlights of 300-Mesh Slag VRMs

✔ Grinding Pressure – 50-120MPa hydraulic system ensures thorough particle breakdown
✔ Hot Gas Integration – 300-400°C waste heat utilization from adjacent processes
✔ Vibration Control – Advanced sensors maintain ≤2.0mm/s vibration for stable operation

Operational Economics (Per 100TPH Unit)

• Power Consumption: 23-28kWh/ton (vs. 38-45kWh in ball mills)

• Maintenance Cost: $0.15-0.20/ton (50% lower than horizontal mills)

• Footprint: 15×20m base (60% space savings)

End-Product Applications

• GGBFS (Ground Granulated Blast Furnace Slag) for cement replacement

• Micro-powder additives in asphalt and concrete

• Soil conditioners in agriculture
